HandBrake

Rec709 is SDR. Re2020 is HDR. I don’t know what the menus look like (not at my computer). But use that I got to select the right choice.

To continue, I think handbrake downmixes to 48khz. The 16/24 bit is irrelevant because you are using a lossy codec (AAC)

As far as an input, both DTS-HD and TrueHD are virtually identical as far as audio quality. And encode as 256Kbs or higher to retain as much audio quality. As far as the down mixing to stereo, I use just stereo. It won’t erase any of the tracks, but mix them to left and right. For a while there ther...

Think of a picture on your computer. If it's encoded as a bitmap image, there is no compression leading to larger file size. A jpeg would be an encoding that compresses the file to shrink the file size. compression can be lossy, where information about the picture/video/audio is thown out to represe...

Think of encoding as "make file format". Compression is "make file smaller". You can encode with or without compression

There is no curve. Very fast files may be similar or even slightly larger than slower settings. As I said before, the faster settings use as many bits as needed to get a decent picture and moves on. It won’t try to compress any further. As far as picture quality, the difference is there, but very su...

You have to remember that file size does not mean quality. The faster settings are designed to just throw enough bits to display the image good enough, and not further see how better to compress. It does its thing and moves on. It doesn’t try to save bitrate, just encoding time. It’s why it’s the fa...

You do not want to do lossless encoding. All I want to ensure is that no quality is lost, and I don't trust my eyes to be the judge of that. If you want no quality loss, just keep the original rip. Handbrake will make sacrifices to encode the file. And you cant tell the differences during playback,...

I think you misunderstand. You don’t have to abandon handbrake. Handbrake and makemkv are 2 programs with different goals in mind. Handbrake compressed video into h.264 or h.265. When you ripped dvds with it, it’s not the original file. It been changed into a different format with some loss in quali...

Handbrake hasn't been able to rip commercial DVDs in over a decade on its own. There was a plugin (libdvdcss) that could be installed that you may have installed years ago or copied from VLC, that can allow handbrake to read commercial dvds. But its old and has issues reading many newer copy protect...

Handbrake can’t rip directly from commercial dvds. Try ripping with makemkv and send that file to handbrake.

and chage the comb type to BOB if its 60i footage or turn on detelecine if its a film at 24fps for best results and not drop any frames

It is entirely possible. On Blu-ray or 4k blue-ray, the studios have tons of room to just throw the highest bit rate without care to give every frame the best possible quality. Even though that high of bit rate is not needed to maintain most of the image quality. It’s over kill on purpose. Handbrake...

I’m guessing the flickering lines are from the deinterlacer. I’m also assuming that is a telecine version of your cartoon. To minimize the flicker, try using the detelecine filter to get a nice 24fps output. But that won’t Guarantee a flicker free output. You are dealing with interlaced video and So...

The decomb filter does output half resolution, but only on frames that it decombs. But I think it does a pretty good job of smoothing it out that it’s really not that noticeable. But back to solving this. First of all each encode causes quality loss. To minimize, use A preset like production to feed...

Expanding on my replay. In a 2:3 pulldown video, one film frame in that cadence does not exist entirely on one full video frame, but is split between 2 video frames. That’s why we are getting the combing. The filter is operating correctly, just too many cuts in succession is messing up the cadence. ...

Well the video 2:3 cadence would get changed at every cut since it was edited with the 2:3 pulldown in a 29.97 time line. It does look like that the detelecine is confused on the cadence and merging the wrong frames at times. Which makes sense. Looks like a what needs to happen is check for interlac...

What you are experiencing is the bane of interlaced content. Your home movies on vhs are actually 60 (59.94 to be exact) fields per second. Effectively 60 half frames per second. So when encoding to 29.97, you are dropping every other field. Basically throwing out half the temporal information. To f...

While handbrake does compress video. But the input file determines the compression amount. If you are feeding a already highly compressed file, there won’t be much data left to throw out or even worse, To preserve quality, may increase the file size. That’s why we need logs to see what you did.

Final analysis. I think dvd is sub sampled per field. So lines 1&3 share color data and 5&7 share color data ect ect. On top of that you have lines 2&4 ect ect sharing color data. When played back properly deinterlaced, or on a analog tv, this is no big deal. It’s why bob deinterlacing i...

Also old analog tv had this issue as well. The pattern would show up as a minor rainbow pattern in the color signal in high frequency color patterns. Color on analog tv was also encoded at a lot lower resolution.

To answer the original question, it looks like a morie pattern mixed with chroma sub sampling. The high details don’t line up with the pixel grid and capturing color at 1/4 the resolution. If the image was scaled down, the pattern can be made worse, and compression only exacerbates it.

Also what shows, knowing that can help with what deinterlacing Method to use. If it’s a 24 FPS hard telecined, you want to turn on detelecine as your deinterlace meathod. This sounds like your issue with the 24fps cadence going out of sync. 30fps shows like certain sitcoms don’t need any deiterlacin...
